So I have 3 valve options for return flow. One is for the main returns, one is for the spa returns (actually not a spa but part of main pool with a shelf for sitting and a couple spa return jets), and one is for both.
Which setting should I leave it on for best flow? I suppose if I wanted to aerate I could use the spa jets, but for normal operation, how I can I determine which gives the best flow?
